My right eye is corrected as much as possible given the cataract but there is some distortion. It is also my dominant eye so the merging can get strange. I used to wear multifocal contacts that worked really well but didn't go back to them after the repair job. They don't work for all people though.

I just took a closer look at the label and see the Vitamin A content is 100% beta carotene at 4296 mcg 2-tablet single serving dose, over 400% RDA. That's outright high risk, too much actually for no restorative effect at all, and modest effectiveness of preventing MD progression. If you take a look at Centrum, a GlaxoSmithKline product, people who know about all there is to know about pharmaceuticals and actually make major breakthroughs in the science, their product is 1050 mcg daily, 117% RDA, and only 29% is derived from beta-carotene. That is a much saner product that will help you without sending you to any early grave. https://www.centrum.com/learn/vitamins-minerals/vitamin-a/ There're a bunch of ill-health problems that impair absorption of Vitamin A. Liver disease is a big one: What are the causes of vitamin A deficiency? Coeliac disease. Crohn's disease. Giardiasis - an infection of the gut (bowel). Cystic fibrosis. Diseases affecting the pancreas. Liver cirrhosis. Obstruction of the flow of bile from your liver and gallbladder into your gut thyroid dysfunction others Another thing to watch for is deficiency due to medication. Here's an exhaustive list of everything: https://lpi.oregonstate.edu/mic/drug-nutrient-interactions Another way to kill yourself: Some products that may interact with this vitamin [A] include: acitretin, alitretinoin, bexarotene, cholestyramine, isotretinoin, tretinoin, other products that contain vitamin A (such as multivitamins), warfarin. Avoid taking vitamin A at the same time as you take neomycin, orlistat, and mineral oil. https://www.webmd.com/drugs/2/drug-1259/vitamin-a-oral/details> > I was disgnosed with major MD and got a pretty gloomy lecture about my > future.
